Chinese carrier Zhejiang Loong Airlines has firmed its order for 20 Airbus A320 aircraft.
The deal accounts for nine A320neos and 11 baseline A320s.
The agreement follows the memorandum of understanding that was signed in September at the Aviation Expo in Beijing. Deliveries of the aircraft will begin in 2015, says Airbus.
The Chinese carrier has also started commercial operations with a leased A320, becoming the latest Airbus operator in China.
